If an employee, for example, has proven on multiple occasions that he/she is dependable and can handle difficult times elegantly, in my native language we call this person "a man/woman of difficult situations".
Does this phrase sound idiomatic in English? And if not, is there a phrase or expression that can be used to describe that person?
Best Answer
As the other answer states, your suggestion is not idiomatic English and would not generally be understood.
An alternative would be [a] good [person/man/woman] in a crisis, for example Mary is a good woman to have around in a crisis or Max is good in a crisis, which matches what you want, as far as I can tell from your question.
